MFC : Font too large on PC but ok on laptop

Question

I am creating a CFont which is larger than usual :

font1.CreateFont(54, 0, 0, 0, FW_HEAVY, false, false, 0, ANSI_CHARSET, 
OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, FIXED_PITCH|FF_MODERN,
_T("Courier New"));

And set a CEdit control to use this :

m_cEditLimit.SetFont(&font1);

This font was showing ok on the laptop when I was writing the app, but now that I am testing on a regular pc it shows too big and won't fit :

enter image description here

How can I make the font look good on every pc the app is running on ?

You need to use a font size that adapts to the system settings. See http://stackoverflow.com/questions/10268470/calculating-the-logical-font-size — Mark Ransom, Aug 06 '12 at 19:12

Instead of using a hard-coded 54 for the font size, try calculating the size based on points:

int points = 32;
pix = -MulDiv(points, GetDeviceCaps(hdc, LOGPIXELSY), 72);

Adjust points as necessary until the font fits. Now it should be consistent between systems.
